No, the reason is that the signals are routed _through_ the modulator (where they are used to generate the RF and the composite signal) and this degrades the signals. Depending on the modulator in your C64 and the monitor you use, the difference can be quite striking. On the C16 the modulator feeds part of the chroma signal back onto the Luma signal which means you can't really use S-Video at all without artifacts.
